When a toilet is flushed, bath plug pulled out etc, the water leaves the
house via the 5in pipes.
Where does it go?

I have always assumed that it makes it's way back to a plant somewhere for
treatment.

Then what? Is it put back into the system or flushed into the sea? Some will
leak so that ends up in the water table I would expect.

Where is the environmental disaster?

ISTM that there will always be the same amount of water, it simply moves
about a bit.

Feel free to point out the flaws in my thinking.
